START of the EVENT
A Special Focus Meeting on “LCLUC and water resources in coastal zones and Western Ghats”-January 7-8, 2013
Background: The increasing population pressure has created adverse environmental changes and a subsequent impact on the total eco-system of this region, especially on fresh water resources.

Land-Cover/Land-Use Change Program
• LCLUC is an interdisciplinary scientific theme within NASA’s Earth Science program. The ultimate vision of this program is to develop the capability for periodic global inventories of land use and land cover from space, to develop the scientific understanding and models necessary to simulate the processes taking place, and to evaluate the consequences of observed and predicted changes

• LCLUC: Drivers of Disturbance/Stress
• LCLUC Consequences/Impacts
• Change in Land-Use Pattern – Kerala Context • Currently, agriculture has shrunken into a minor sector
offering limited employment • Transition from the agriculture oriented to fishery and
shrimp farming or fish processing • Transition from the agriculture oriented to fishery and
shrimp farming or fish processing • Mangroves in Kerala have been significantly impacted
by Urbanization

• Presented the LCLUC in Trivandrum, Kollam & Palakkad Districts.
• Informed the reduction in agricultural land and increase in built area with time.
Discussions in progress
THE TEAM
FIELD VISITS
• SAROVARAM PARK-Eco-friendly bio-park meant for conservation of wetlands through eco-friendly tourism interventions by sustainable methods.
• KAPPAD BEACH – Rock-studded beach. Gateway to the Malabar coast. Place where Vasco da gama landed first in India
• KADALUNDI BIRD SANCTUARY-Spread over a cluster of islands, surrounded by hillocks. More than 100 species of native birds and 60 species of migratory birds flock during Oct-Mar.
• Experienced Chaliyar river & Beypore traditional sea vessel building unit
SUGGESTIONS & RECOMMENDATIONS
• Improve awareness of the availability of various types of data
• Easy access & availability of ISRO & NASA Data
• International cooperation between ISRO & NASA on sharing of data
• Free & open sharing of data for researchers & students
• University-Organization collaboration/capacity building for using the available data for landuse change research
• Supporting the LCLUC analysis with socio-economic data to understand the influence, impacts and implications of LUC
• Dynamics of the social process has led to the large-scale conversion of paddy
• Land at present is seen only as a real estate needed for residence and status and it is also considered as the safest and best investment
• Spatial data from multiple sources are to be assimilated to make timely assessments and long-term monitoring of LUC.
• In India we have different node specification and theme specification under NRIS, NNRMS as well as NS(G)DI; We should standardize and move ahead…….
